Patch-mainline: v4.16-rc1
References: FATE#322643 bsc#1055900
No-fix: da943b5ab071584fcb9cfa896dc8c643d376f362
While moving code around for solving lockdep issue for GuC log relay,
spotted that uc_fini_wq is not being called in failure path in gem_init.
Missed in the below commit. Add it.
V2: Removed GEM_BUG_ON(!HAS_GUC()) from intel_uc_fini_wq as init happens
only based on enable_guc module parameter and does not consider has_guc
capability. (Michal)
